Question

Consider the circuit shown below. Write a short analysis of whether or not it will work as designed. If you think that it won't work, discuss what changes you would make to the circuit to fix the problem(s). The curve of drain current versus gate to source voltage, Vos for the MOSFET is given for your reference on the next page. The maximum Drain to Source voltage of the MOSFET is 300 Volts and the maximum drain current is 5 A. The 2N2222A transistor has a maximum collector voltage of 30 volts and the value of the DC current gain, he (beta) is 50. The maximum collector current for the 2N2222A is 100 mA. The microcontroller LO pin can source up to 500 μΑ (@ 5 volts or sink up to 500 μΑ at 0 volts. 100 VDC 50 K Microcontroller 1 M WA2N2222A 75 ohm I/O pin MOSFET 70 r 60 50 40 CD 는 30 o 20 10 0 10 6 8 0 Gate-source voltage VGs (V)
